Analysis of Means for Reliability Characteristics
نویسندگان
چکیده
Analysis of Means (ANOM) is a rational extension of the Shewhart control chart for comparing products from different design configurations in off-line quality improvement. ANOM is a powerful graphic-tool for engineers to present and interpret experimental results. We apply the ANOM idea to the analysis of lifetime data resulting from experiments planned for enhancing product reliability. The maximum likelihood method is utilized to estimate parameters of the Weibull and lognormal distributions for interval censored and accelerated life-tested data. Decision limits for the ANOM chart are constructed using quantiles of the distributions of the pivotal statistics. Asymptotic results are derived for comparison with the finite sample inferences obtained by Monte Carlo simulations.

Reliability Analysis of Switches and Crossings – A Case Study in Swedish Railway
It is reported that switches and crossings (S&C) are one of the subsystems that cause the most delays on Swedish Railways while accounting for at least 13% of maintenance costs. It is the main reason for choosing to base this study on this subsystem. Intelligent data processing allows understanding the real reliability characteristics of the assets to be maintained. The first objective of this...

متن کاملBayesian Estimation of Reliability of the Electronic Components Using Censored Data from Weibull Distribution: Different Prior Distributions
The Weibull distribution has been widely used in survival and engineering reliability analysis. In life testing experiments is fairly common practice to terminate the experiment before all the items have failed, that means the data are censored. Thus, the main objective of this paper is to estimate the reliability function of the Weibull distribution with uncensored and censored data by using B...
